Coming to reading technology without turning the page

Researchers at MIT and Georgia have created a system that allows you to read books without having to flip pages one by one. It can read up to nine pages and separates the first 20 pages of a book.

It sounds like the technology is like an x-ray or ultrasound scan, but terahertz radiation recognizes the image of the ink and then tells the system what the shape looks like. Meanwhile, X-rays do not distinguish between paper and ink clearly, and ultrasound does not provide a sufficiently high resolution. To help distinguish pages from one page to another, terahertz radiation uses the ability to recognize space between pages with a minimum size of 20 micrometers.

The terahertz radiation technique will help people know the content while not harming the object.

The technology will be further developed in the future. Their current goal is to increase the accuracy of the system, and to improve the forward source for increased penetration and recognition on more pages.

The practical application of this technology is not too difficult to predict: in the museum there are some old books that are stuck together or difficult to open the cover, so terahertz radiation will help people We know the contents while not harming the antiques.

Terahertz radiation can also be used to analyze paints in a work of art or overlapping antique materials.
